Nope. It's noble, in my opinion.
Yes, in a way it is bcuz you're only thinking of yourself at that moment
it basically comes down to quality of life.
Nothing selfish about it. I hate when people associate "feeling so sad you don't want to live" with "selfishness" but what they do mean it is often the case, they leave behind their loved ones feeling very hurt by their death. I think life is worthwhile. Suicide is a permanent solution to only a temporary problem. There's much in life to experience and those are the things that can really make a life turn around and make it worth while.
Are you going to clean up after yourself?
Yes because there are people who are affected by this that they may not even know about. Not only is it selfish it's naive.
no it takes everyone into account
only the recipients care, no?
Not at all.
Depends on the situation.
